The UCC commitment to quality is backed by thousands of hours of development, testing and evaluation. United Conveyor Corporation has one of the world's most advanced research laboratories and conveyor test loops to simulate ash and reagent handling applications and validate design parameters. Our knowledge and experience in material behavior, product innovation and system development for challenging applications is unmatched in the industry.
UCC works closely with our global customers to test and verify conveying performance before deployment at the plant to effectively manage risk.
Technology
Our test lab provides UCC’s NPD team with the capability to engineer prototypes and continually test new products and equipment to enhance existing designs. This ability enables our engineers to develop state-of-the-art technology, providing our customers with superior products and custom solutions they’ve come to expect from us.
Material Testing
Hundreds of ash and reagent samples have been tested and analyzed in our 10,000 sq. ft. lab to ensure material performance and reliability. This testing environment allows for complete analysis of physical, chemical and conveying characteristics of material.
Testing Includes:
- Bulk Density
- Particle Density
- Fluidizability
- Sieve Size Distribution Level
- Microscopic Examination with Digital Photography
- Setup/Conditioning
- Pick Up Velocity
- Arching/Ratholing Index
- Permeability/Deaeratability
| - Moisture Content
- LOI or Unburnt Carbon
- Scanning Electron Microscope (SEM) photography
- Particle size distribution under 44 microns
- X-Ray fluorescence (XRF)
- Free-lime test
- Water tests – Langelier’s index, Ryzner stability index, Aggressiveness Index

Test Loops
Our facility contains six complete test loops which are used to simulate the behaviors of material in conveying lines under various conditions. Control systems are used to examine and control the conveying environment, and comprehensive data is collected and provided to verify determining design parameters.
